IMPROVEMENT IN INJECTORS.

Specification forming part of Letters Patent No. 215,544, dated May 20,1879; application filed April 9, 1879.

struction an actuating-nozzle, a combiningtube, and a discharge-tube andthe improvement consists in constructing the apparatus with an annularactuating-nozzle, combiningtube, and discharge-tube, concentric witheach other, and so arranged that the liquid or fluid is admitted to thecombiningtube both from the inside and outside.

In the accompanying drawings, Figure 1 represents a vertical centralsection of myim- .proved apparatus, and Fig. 2 a similar view of acommon form of jet apparatus which I sometimes use in connection with myimproved apparatus.

As commonly constructed, the shape of the different nozzles and tubeshas been such as to necessitate certain distances and lengths of thecombining and discharge tubes, proportioned to the diameter of theapparatus, in order to insure a perfect mixing or condensation of theactuating liquid or fluid with the liquid .or fluid to be moved, withoutwhich proportionin g of parts a proper action of the apparatus could notbe obtained; and for this reason the size of the apparatus whenconstructed in the usual manner is necessarily limited, for obvioustheoretical and practical reasons.

Experience demonstrates that the less the diameter or thickness of theactuating-jet and that of the liquid or fluid to be moved is the.quicker, more perfect, ,and effective will be the condensation or mixingof the liquids or fluids.

With this fact in View, I construct my apparatus as represented in Fig.1, consisting of an annularactuating-nozzle, A, an annularcombining-tube, B, and an annular dischargetube, 0, combined in suchmanner that the liquid. or fluid to be moved is admitted both from theinside and the outside into the combining-tube, as indicated by thedotted arrows.

X is the inlet for the actuating liquid or fluid; Y, the inlet orsuction, and Z the outlet.

From the discharge-tube G theliquid enters the annular chamber D, whichcommunicates, through the passages D, with the annular chamber E, fromwhich it is discharged through the outlet Z. I

Where the volume of the actuating-jet is very small in proportion to thevolume to be moved, it may be necessary or advantageous, for practicalreasons, to combine with this apparatus one of ordinary construction,such as represented in Fig. 2, or of any other wellknown type, eitherwith a single nozzle or a series of nozzles. In such case the dischargeend of the apparatus shown in Fig. 2 would be arranged toconnect withthe inlet X of Fig. 1, through which the actuating liquid or fluidenters.

Having thus'described my invention, what I claim is- I A jet apparatuscontaining an annular actuating-nozzle, an annular combining-tube, andan annular discharge-tube, arranged in such manner that the liquid orfluid is admitted into the combining-tube both from the inside andoutside, substantially as shown.
